The
Pico Ring
from
Erica Synths
adds a four-quadrant ring modulator with internal modulation oscillator to the narrow Eurorack line. The analog circuit processes audio and CV signals, but is most effective when two oscillators with sine waveform are used at the inputs. The built-in sine wave oscillator, whose pitch can be manually adjusted, ensures a lot of results with little effort. If no cable is plugged at the inputs, the internal sine oscillator is passed directly to the output and is thus available as a modulation source for other modules. Soundwise the sounds range between bell-like, metallic and industrial scenery.
